INSULATOR.

Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed March 8, 1917. Serial No. 153,447;

To all whom it may concern:

Be it known that I, CLYDE T. DE VAUGHN,

a. citizen of the United States, residing at Parkcrsburg, in the county of Wood, State of West Virginia, have invented certain new and useful Improvements in Insulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in insulators, designed primarily for use in connection with telephone and telegraph wires.

An object of the present invention resides in the provision of an insulator embodying means of novel construction and arrangement for the attachment of line or other wires without the use'of tie wires .or similar binding means.

The invention further embodies a novelly constructed insulator with and from which the line wire may be quickly and conveniently engaged and disengaged; one which in addition possesses the desired features of simplicity, efficiency and reliability and which may be manufactured and installed at a relatively low cost.

With the above and other objects of similar nature in view, the invention consists in the construction, combination and arrangement of parts set forth in and falling within the scope of the appended claim.

In the drawing:

Figure 1 is a side elevation of my improved insulator illustrating its use,

Fig. 2 is a similar view taken at right angles to .Fig. 1,

ig. 3 is a vertical section on line 2-2 of Fig. 1 of the drawing.

Fig. 4 is a section taken on the line 44 of F1 3.

Ret erring now more particularly to the accompanym drawing, the insulator is shown genera l at A and comprises a body member 5 whic may be made of porcelain, glass or other suitable non-conducting material and is provided in its base with a tapered and threaded socket 6 for a purpose to be presently explained. The insulator body 5 is provided adjacent its top or head portion with a transverse passage 7 preferably of rectangular cross-section and communicatingwith the socket 6. An open slot 8 is provided in the upper portion of the body 5 which communicates with the passage 7 its purpose being to permit the convenient insertion and removal of the line wire into and from said transverse passage.

For securing the line wire within the passage '7 there are provided a pair of separable wire gripping elements 9 and 10 respectively, of a non-conducting material similar to that of the body member 5. These gripping elements 9 and 10 are removably inserted into the transverse passage, and are respectively disposed above and below the line wire, their combined size, when so positioned, being such as to approximately fill the passage, while their opposed faces are provided with registering longitudinal grooves 11 into which the line wire seats.

Formed on the upper face of the element 9 is an integral rib 16, which, when the element is in operative position, serves to close the slot 8 to the weather, lugs 17 being also formed on said'element at each sideof the rib and adapted to seat in depressions 18 provided in the upper Wall of the passage 7, whereby to prevent longitudinal displacement of the element from the latter as will be readily understood.

In order to suitably attach the body mem her 5 to the usual cross-arm or other support, there is provided a bolt 13 passed through and secured to the cross-arm as clearly shown, while mounted to rotate freely about the bolt between its head 14 and the cross-arm is a tapered and threaded pin 15, the upper end of which is slightly counter-sunk so that the head 14 will seat therein but project above the pin.

When placing the line wire and gripping elements 9 and 10 in the transverse passage, the body member 5 is only engaged loosely upon the pin 15, but assoon as they are properly positioned, the pin 15 is rotated on the bolt 13 to tighten the body member thereon, the head 14 of the bolt being thus caused to bind in the recess 12 in the element 10 and force the gripping elements in clamping relation to the line wire, and at the same time prevent longitudinal displacement of said element from the body member.

What I claim is:

An insulator for electric wires comprising a non-conducting member provided with a threaded socket and having a transverse wire receiving passage communicating with the socket, spaced Wire gripping elements gripping relation to the Wire and against 10 remotably inserted in the passage, one of displacement from the passage.

said elements having a recess therein regis- In testimony whereof, I affix my signature tering with the socket, a pin threaded in the in the presence of two .witnesses. socket, and an attaching bolt passed loosely CLYDE T DE VAUGHN through said pin with its head positioned to enter and bind in the recess when the pin Witnesses:

is tightened in the conducting member, H. G. BUTCHER, whereby to hold the gripping elements in F. M. BECKWITH.
